What is DTF? The DTF can allow you to print easily on cotton, polyester, synthetic, or silk without any trouble. Transfers can work on both dark and white fabric. This pre-made sheet of 11 t-shirt transfers is ready to be used right out the package. This is the perfect way to save time and money by using our transfer for all of your projects! Simply separate your image, place it face down on the shirt, heat press and peel off! Transfers range from 10-11 inches wide. Step by step instructions will be included.
